Description
Technical Field
The present utility model relates to an exhaust gas purifying apparatus. The tower body structure of the section of waste gas purifying tower where the waste gas inlet is suitable for the waste gas purifying tower for purifying waste gas generated by the electroplating production line.
Background
It is known in the electroplating industry that exhaust gas purifying towers, i.e. spray towers, are common equipment used for purifying exhaust gases. At present, the air inlet structure of the waste gas purifying tower used in the electroplating industry is a traditional air inlet structure. The traditional air inlet structure comprises a tower wall and an air inlet arranged on the tower wall, wherein the tower wall is of a single-layer structure. The air inlet is provided with an elbow, the outer end of the elbow, namely the air inlet, is horizontally arranged, and the air outlet extends into the tower body and bends downwards, so that an included angle of 90 degrees is formed between the inlet and the outlet. When the device works, the treated waste gas enters the air inlet from the lower part of the tower wall horizontally, and then flows downwards by 90 degrees to the lower part of the tower body. Then, the waste gas is blocked by the liquid level at the bottom of the tower body, turns 180 degrees and flows upwards, and performs gas-liquid exchange with the spray liquid in the packing layer, so that pollutants in the waste gas are transferred into the spray liquid, and the waste gas is purified. It can be seen that there is a 270 degree bend in the exhaust gas from the inlet to the packing. The exhaust gas has a larger resistance to advancing due to 270 degrees of turning from the air inlet to the packing layer. And the power of the fan is required to be high as soon as the resistance of the waste gas is high. The power of the fan is high, so that the energy consumption is high, and the purification treatment cost of the waste gas is high.
Because the waste gas has 270 degrees of turning from the air inlet to the packing layer, the waste gas is strong and weak at each point of the section of the tower body, so that the local wind speed is too high, the disturbance of the packing layer is easy to cause, the flow speed of the waste gas at the position is further accelerated, and finally the spraying liquid at the position is brought out of the tower body, so that not only can the flooding phenomenon be caused, but also the purification effect of the waste gas can be reduced.
Disclosure of Invention
The utility model aims to overcome the defects and provide an air inlet structure of an exhaust gas purifying tower. By adopting the air inlet structure, the purification treatment cost of waste gas can be reduced, the flooding phenomenon is avoided, and the purification effect of the waste gas is improved.
The above problems to be solved by the present utility model are achieved by the following solutions:
the exhaust gas purifying tower air inlet structure comprises an outer tower wall, wherein an air inlet is formed in the lower portion of the outer tower wall. The method is characterized in that: an inner tower wall is arranged in the outer tower wall. The inner tower wall corresponds to the outer tower wall, and a space is reserved between the inner tower wall and the outer tower wall in the circumferential direction. And air distribution holes are uniformly distributed on the wall of the inner tower. A connecting plate is arranged between the lower end of the inner tower wall and the outer tower wall. The connecting plate is an annular plate, the width of the cross section of the connecting plate is matched with the distance, the periphery of the outer side of the connecting plate is connected with the inner side face of the outer layer tower wall, and the inner side of the connecting plate is connected with the lower end of the inner layer tower wall.
Wherein, the width centre of even board has the through-hole, and this through-hole is along even circumference equipartition of board.
According to a further improvement scheme of the utility model, the outer side face of the inner layer tower wall in the height direction is provided with a reinforcing ring, and the inner diameter of the reinforcing ring is equal to the outer diameter of the inner layer tower wall and is fixed together.
According to the scheme, the inner tower wall is arranged in the outer tower wall, and a gap is reserved between the inner tower wall and the outer tower wall in the circumferential direction. And air distribution holes are uniformly distributed on the wall of the inner tower. The air inlet at the lower part of the tower body is not provided with an elbow, so that waste gas entering the outer tower wall from the air inlet is opposite to the inner tower wall. And air distribution holes are uniformly distributed on the inner tower wall, and after the waste gas entering the outer tower wall from the air inlet is uniformly distributed through the inner tower wall, the waste gas can reach the packing layer in the tower body to exchange gas and liquid with the spray liquid in the packing layer only by turning upwards by 90 degrees. Compared with the prior art that waste gas entering the tower body from the air inlet can reach the packing layer in the tower body through 270-degree turning and carry out gas-liquid exchange with spray liquid in the packing layer, the resistance of the waste gas in the advancing process can be greatly reduced. And as soon as the resistance of the exhaust gas is reduced, the power of the required fan is small. The power of the fan is small, the energy consumption is low, and the purification treatment cost of the waste gas is low.
And because the waste gas only turns 90 degrees from the air inlet to the packing layer, the strength of the waste gas at each point of the section of the tower body is uniform, the disturbance of the packing layer and the condition that the spray liquid is carried out of the tower body are avoided, the flooding phenomenon is avoided, and the purification treatment effect on the waste gas is improved.
